ive been going back and forth on this on whatsapp since april 9th (the day i received it). it's totally unacceptable to be having these kinds of issues on a device that costs this much.
i will say that audio is better with the latest version, but still not perfect. there is a slight echo every (always on the person im talking to hearing themselves) so often but not near as bad as it was. the biggest issue is that people tell me i sound like i'm in a wind tunnel. i finally figured out that it's picking up the a/c. if you turn it off everything clears up (not an option in the georgia heat). people dont say the same thing when i have my phone directly connected to the tesla over bt, so not sure why it's different.
the biggest issue i'm having now is the fact that the hsu loses bluetooth connectivity almost every time i get in the car. i have to forget the device from my phone and repair my phone back through bluetooth. if they can fix these two issues, i think we'll be good to go.
